I don't have the source handy, but I remember reading that during his lifetime, Euler was responsible for one third of the entire world's output of new work in the Mathematical Sciences (Maths, Physics and Optics I guess).

ONE THIRD!

(I think it was from this book: http://www.amazon.com/Journey-through-Genius-Theorems-Mathem...)

sudo ln -s /usr/bin/mate /usr/bin/mate_wait export EDITOR="mate_wait"

"mate_wait" does not need a "-w"

I had a problem recently where crontab -e didn't like mate. mate_wait seems to work as an EDITOR value everywhere.

Not really. There are better git tutorials out there - http://osteele.com/del.icio.us/osteele/git (from the article).

Git allows you to choose which way you work more than (say) subversion. This article is an example of a slightly different way to work.
